To all whom it may concern:

Be it known that I, FRANK G. Sonrnnr, a citizen ,of the United States, residing at San Santa Clara and State of California, havejinvented new and useful Improvements in Hydrocarbon-Burncrs, of which the following is a specification.

This invention relates to hydrocarbon burners, particularly adapted for use in connection with cooking stoves, heating stoves,

'steam boilers, steam heaters and for other purposes wherein it is found applicable; and the object. thereof is to provide, in a manner as hereinafter set forth, a hydrocarbon burner with means whereby the oil will be fed steadilyand enable the vapor to be generated in an even manner, thereby causmg a uniformllalne at the outlet or burner. I 'A further object of the invention is to provide a hydrocarbon burner, in a manner as hereinafter set forth, with means to confor dividing the flame so that the bottom and thereby a quick generation'of vapor.

Further objects of the invention are to provide a hydrocarbonburner for the purpose set. forth, which shall be simple in its construction, strong, durable, efficient in its use, readily set up and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter more specifically described andiillustrated in the accompanying drawings, wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope "of "the claims hereunto ap ended. my

n descrrolng the invention in detail referenceis had to the accompanying drawings, wherein like characters denote corresponding parts throughout the several views, and in wnich- Fi 'ure 1 is a longitudinal sectional view of a hydrocarbon burner in accordance with this invention; Fig. 2 is a top lan showing 7 the oil supply pipes, these latter sing broken away; Fig. 3 1s an inverted plan of the oil- 'recelving chamber showing the arrangement 0' one form of deflector; Fig. a like-view showing a modified arrangement sides of the oil-receiving chamber will be heated, causing of deflectors; Fig. 5 is a similar view of another modified arrangement of deflectors; Fig. 6 is a view similar to Fig. 3 ofa modified arrangement of deflector, and, Fig. 7 is a view of a modified construction of burner.

Referring to the drawings by reference characters, 1 denotes a cylindrical receptacle forming a combined oil-rcceiving and vaporizing chamber 2.

3 denotes a hollow ring substantially square in cross section and forining a circular vapor heating chamber 4 and forming an opening 5. The recc )tacle 1 is arranged over the ring 3 an d the l) her 2 extends over the opening 5 formed by the ring 3, but is positioned at a point above the same.

Connnunicating with the chamber 2 is a series of oil supply pipes 7, 8 and 9 which open into said chamber 2 and are connected to the side wall of said. chamber at points equidistant. The pipes 7, 8 and 9 open into the chamber 2 at a point above the bottom 6 oi said chamber 2. The latter communicatcs with the chamber 4 through the medium of a pipe 10 which is exteriorly screwthreaded and connected at its lower end to the to .1 wall 11 of the chamber 1 and extends into t c chamber 2. The chamber 1 is adjustable upon the pipe 10 so it can be moved towards or away from the chamber 4. This arrangement is made in view of the position of the deflectors between the ring 3 and the receptacle 1. The function of the deflectors will be hereinafter referred to. Preferably, the pipe 10 extends in the chamber 2 at a point above the bottom of the pipes 7, 8 and 9, as shown in Fig. 1.

The reference character 12 denotes an elbow connected to the ring 3 through the medium of the coupling piece 13, the latter being cxtcriorly screw-threaded and engaging in the bottom wall 14 of the chamber 4 and also engaging within the elbow 12. The coupling 13 constitutes an, outlet for the vapor from the chamber 3. Attached to the elbow 12 is a pipe connection 15 which carries a burner .16, the latter being positioned approximately centrally of the opening 5 formed by the ring The burner outlet is indicated by the reference character 17 and is closed through the medium of a needle valve 18. The needle valve 18 also constitutes a means for ulating the quantity of vapor pass-Jig through the outlet 17. The

ottom 6 of the charm stem of the needle valve is screw-threaded as at 19 and passes through a cross piece 20 carried by the burner 16. A fln er-piece 21, is carried upon the outer end of t e stem of the needle valve.

interposed between the receptacle 1 and the ring 3 is a deflector or a plurality of deflectors for dividing the flame in a manner desired, and in Fig. 3 the deflector is indicated by the reference character 22 and it is formed of a circular piece of material extending two-thirds round the bottom 6. The deflector 22 can be of any suitable height and forms an opening 23 between the ring and receptacle 3 and 1 through which the flame is caused to pass. In Fig. 4 a series of deflectors is shown and which are indicated by the reference character 24. The deflectors 24 form a series of openings 25 between the receptacle 1 and the ring 3' and. through which the flame is caused to pass. The deflectors 24 are wedge-shaped in contour. Fig. 5 the deflectors are indicated by the ref erence character 26. Four of the deflectors 26 areshown. Openings 27 for the passage of the flame are formed by the deflectors 26.

These latter are substantially triangular in contour. In Fig. 6 a single deflector is shown which is indicated by the reference character 28 and which passes round substantially half of the bottom 6. An opening 29 betweenthe receptacle 1 and the ring 3 is formed by the deflector -The deflectors are secured to the lower face of the bottom 6 by the holdfast devices 30 and are ositioned at the margin 01" the lower face 0 the bottom 6.

The pipes 7, 8 and 9 are provided with valves 31 so as to regulate the supply of oil to the chamber 2 and the said pipes 7, 8 and 9 are detachably connected to the receptacle 1 so that when removed the openings formed to receive the pipes 7, 8 and 9 can be used for the removal of accumulated matter within the chamber 2. The receptacle 1 is formed with a series of removable plugs 32 (only one of which is shown) so that access can be had to the chamber 3 for cleaning it.

In lieu of employing the construction of burner 16 the burner shown in Fig. 7 may be used. This burner is indicated by the reference character 33 and has an outlet 34. It is connected to the elbow P2 in lieu of the pi e connection 15. The burner outlet 34, w ien the burner 33 is secured to the union 12, is positioned approximately centrally of the opening 5.

i The 'manner of using the burner is as fol- Y lows :Oil being fed to the chamber 2, will flow into the chamber 4 and from there to the burner where it can be ignited. The ignition of the oil will vaporize the oil within the chamber 4- and also the oil Within the After the oil in the chamber 4 has been va orized the flame will act only upon the oil in the '-hamber 2 and the vapor between t independently seaeee vaporized before it is ignited at the burner.

In some instances it has been found that all that is necessary in regard to the heating of the receptacle 1 is to divide the flame so as to contact with a portion only .of the .side wall, and in this connection the deflectors 22 and 28 are used. Furthermore, when the deflectors 22'and 28 are used the flame "iscaused to 1pass around the pipe connection 10 e receptacles 1 and 3. This heats the vapor as itis passing through the pipe.

In other instances it is found necessary to heat the side wall at various portions and for such purpose the deflectors 24 and 26 are used. When the deflectors 24 and 26 are used the flame is also divided so as to pass around the ipe 10 which assists in heating the vapor uring its passage through said pipe.

the regulating valve the oil is supplied to the chamber 2 in a steady and-even manner and causes the vapor to be generated in a uni- ,form manner as the oil is supplied at various oints through the chamber 2 and not in a arge quantity at one point in the chamber. It'has been found that the heat acts more readily-upon the oil when it is evenly dis tributed owing to the em loying of three By employing a pluralityof feed pipes for pipes than it does if a sing e supply pipe is used. a

The deflectors for dividing the flame materially assist in the generating of the vapor, cause the flame to ass from the ppening 5 and contact the wal of the receptacle 1, so under such circumstances the bottom of the receptacle 1 is not only heated, but also the side, consequently materially assisting in the generating of vapor within the chamber 2.

Mounted upon the burner 16 is a cupshaped member 19 for catching any over flow of oil from the burner.

The said cupshaped member 19 is supported and retained in position through the medium of an interiorly screw-threaded cu 19 the latter engaging with periphera screwthreads formed on the burner 16, the cup 19 being secured to the lower portion of the burner 19. Carried by the needle valve stem at a point between the finger piece for adjusting said stem and the lower end of the burner is a beveled inion 19, with which is adapted to mesh a eveled pin on 19 carried on the inner end'of an elongated rod 19 provided with a handle 19 Such arrangement provides for the adjustment of the needle valve of the finger piece 21 and the length of the rod is such as to extend outside of a stove or furnace aiid by such construc= .130

' conveniently tion it is evident that the needle valve can be adjusted without any danger of the operator being burned if the burner is mounted in a stove. The beveled pinion 19 is connected to the needle valve stem in a known manner so that the stem can be vertically shifted through the pinion'19 but at.

the same time be rotated when motion is imparted to the pinion.
